The US Department of Energy (DOE) will invest $20m to support offshore wind development by honing weather modelling used to forecast energy production from lease areas and also demonstrating innovative technologies.

The funding opportunity is among the largest for the sector since President Donald Trump took office in January 2017.

“This funding for offshore wind resource science will improve the weather models that wind plant developers and operators rely on to manage their fleet effectively and provide predictable, low-cost electricity,” said DOE assistant secretary Daniel Simmons.
